Rapid temperature-regulated fermenter

Abstract

The application relates to the field of fermentation tanks, in particular to a rapid temperature regulation fermentation tank. The fermentation tank comprises a fermentation tank body, an external heat exchange unit, a circulating conveying unit and a backflow injection unit. The top of the fermentation tank body is provided with an openable manhole and an exhaust valve, the bottom is conical and provided with a yeast discharge valve, and the sidewall of the tank body is provided with a heating jacket structure. The circulating conveying unit comprises a pump installed on an outlet pipeline at the bottom of the fermentation tank body. The inlet end of the pump is connected to the lowest point of the conical bottom of the fermentation tank body through a bottom liquid pumping pipeline, and is used for efficiently pumping the fermentation mash in the tank. The outlet end of the pump is connected to the mash inlet of the external heat exchange unit. Compared with the prior art, the application significantly improves the overall heat transfer rate by forced circulation and external high-efficiency plate heat exchange, greatly shortens the temperature response time, and greatly strengthens the mixing in the tank through the uniformly distributed high-speed injection backflow.
